SUNSET: 
See the Stars with Worldwide Eyes
Have you ever wanted to try "virtual observing"? Here's your chance! This weekend you can view fabulous deep-sky objects in both the northern and southern sky by logging on to a special two-day event spearheaded by Astronomers Without Borders
Eclipsing in the New Year
Skywatchers in Europe and Asia saw more than fireworks when they looked up on New Year's Eve.
December's Blue Moon? Bah, Humbug!
This month brings full Moons on the 2nd and 31st — a doubling-up that's neither rare nor noteworthy.
A Great Year for Geminid Meteors
When nature puts on a great show, why not watch? The Geminid meteors, which peak on December 13-14, may not be as famous as August's Perseids, but they're just as bountiful.
January 11th's Morning Antares Occulation
On the morning of January 11, 2010, people in northeasternmost North America can watch the Moon cover Antares for the last time until 2023.
The 2009 Leonids Are Coming!
The Leonid meteor shower peaks near new Moon in 2009, making this a fine year for any meteor lover. Observers in the Americas are ideally placed for the traditional peak, and a brief, unusually intense burst is forecast for Asia.
The Orionid Meteors are Here!
October's Orionid meteor shower isn't one of the year's richest, but it's a chance to see bits of dust shed long ago by Halley's Comet colliding with Earth's atmosphere. For the next few nights, with moonlight not a factor, you might spot an Orionid every few minutes from a dark-sky location.
Planet Trio Dances at Dawn
Jupiter, the King of Planets, has the evening sky pretty much all to itself. But three other planets — Venus, Mercury, and Saturn — are putting on quite a show in the east before dawn.
Get Ready for "Galilean Nights"
Galileo saw some amazing sights when he turned his telescope to the heavens 400 years ago. Now you can relive his discoveries — and share the excitement with others!
Citizen Science: Projects & Collaboration
Citizen Sky Wants You!
Backyard astronomers of all types and experience levels can participate in a real-world science project — and help solve a mystery involving the star Epsilon Aurigae that's puzzled astronomers since 1821.
"Lights, Camera, Cue the Moons!"
Check out the impressive interplay of Io, larger Ganymede, and Io's shadow during a remarkable pairing of these Jovian moons captured on August 16th.
Perseids Perform Beautifully!
Despite moonlight, this year's Perseid meteor shower has been pleasing millions worldwide.
"Barely There" Lunar Eclipse
If you forgot to check out last night's penumbral lunar eclipse, you didn't miss much!
Perseid Meteors by Moonlight
Mark your calendar for August 11th and 12th — even though a last-quarter Moon horns in on the annual show.
Jupiter Blots Out a Star
From August 2nd to 5th, the 6th-magnitude star 45 Capricorni masquerades as a fifth moon of Jupiter, forming striking patterns with the Galilean moons. And at the peak of the action, the star passes behind Jupiter's disk.
Totality on a Tropical Sea
More than 1,000 eclipse-seekers watched totality from a specially chartered ship that had steamed into the western Pacific for the "Eclipse of the Century."
Kaguya To Hit the Moon
On June 10th at 18:25 Universal Time the Japanese lunar orbiter Kaguya is ending its two years of science with a final impact experiment. Astronomers are poised to capture the crash.
A Daring Pairing of Moon and Venus
Early risers today have a chance to see this beautiful crescent Moon slide past Venus in the dawn sky. This view by Johnny Horne was captured at 5:34 a.m. EDT at Wade, North Carolina
Venus at its 8-Year Best
Venus spent the last nine months as the Evening Star, but it's now faintly visible to the unaided eye just before sunrise — and possibly also just before sunset on the same day. For telescopic observers, this is the most exciting possible time to view Venus during broad daylight. But when doing this, be super-careful not to look at the Sun and blind yourself!
